From south to north the Himalaya (Himalaya orogen) is divided into 4 parallel tectonostratigraphic zones and 5 thrust faults which extend across the length of Himalaya orogen. Each zone, flanked by the thrust faults on its north and south, has stratigraphy (type of rocks and their layering) different from the adjacent zones.
Because the Himalaya form on the leading edge of a collisional tectonic event, it stands to reason that many structural features will form in this area. The three main rock units: the LHS, GHC, and THS all have a hotly debated relationship with each other involving two main fault lines. One is the Main Central Thrust (MCT), and the other is the ...
In geology, metasedimentary rock is a type of metamorphic rock. Such a rock was first formed through the deposition and solidification of sediment. Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. The overall composition of a metasedimentary rock can be ...
The Main Central Thrust is a major geological fault where the Indian plate has pushed under the Eurasian plate along the Himalaya. The fault slopes down to the north and is exposed on the surface in a NW-SE direction (strike). It is a thrust fault that continues along 2900 km of the Himalaya mountain belt. [1]
The Himalayas, or Himalaya (/ ˌ h ɪ m ə ˈ l eɪ. ə, h ɪ ˈ m ɑː l ə j ə / HIM-ə-LAY-ə, hih-MAH-lə-yə) [b] is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has several peaks exceeding an elevation of 8,000 m (26,000 ft) including Mount Everest, the highest mountain on ...
The Northern Indian State Himachal Pradesh is located in the Western Himalaya (Fig. 1). It has a rugged terrain, with elevation ranging from 320m to 6975m. [2] Rock materials in the region are largely from the Indian craton, [3] and their ages range from the Paleoproterozoic to the present day. [4]
Satellite image of the Himalayas Spatial arrangement of the Himalayan tectonostratigraphic zones. Modified from N.R. McKenzie et al 2011 [1]. Pre-collisional Himalaya is the arrangement of the Himalayan rock units before mountain-building processes resulted in the collision of Asia and India.
The Himalaya orogenic belt the highest elevated mountain range on Earth. In summer, air mass across the South Asia is heated up in general. On the contrary, airmass above the Himalayas and Tibet experiences adiabatic cooling and sinks rapidly, forming an intense high pressure cell. This cell is therefore capable of facilitating landward airflow ...
